How to get data for specific condtion in php curl - php

Question

'url here' which contains a data key and the value is a string which contains items in the format: key=STRING, age=INTEGER. My goal is to count how many items exist that have an age equal to or greater than 50, and print this final value.
$ch = curl_init('url here');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data = curl_exec($ch);
curl_close($ch);
print_r(json_decode($data, true));
$data getting data as follows:
Array
(
[data] => key=IAfpK, age=58,
key=WNVdi, age=64,
key=jp9zt, age=47,
key=0Sr4C, age=68,
key=CGEqo, age=76,
key=IxKVQ, age=79, key=eD221, age=29, key=XZbHV, age=32, key=k1SN5, age=88, key=4SCsU, age=65, key=q3kG6, age=33, key=MGQpf, age=13, key=Kj6xW, age=14, key=tg2VM, age=30, key=WSnCU, age=24, key=f1Vvz, age=46, key=dOS7A, age=72, key=tDojg, age=82, key=nZyJA, age=48, key=R8JTk, age=29, key=005Ot, age=66, key=HHROm, age=12, key=5yzG8, age=51, key=xMJ5D, age=38, key=TXtVu, age=82, key=Hz38B, age=84, key=WfObU, age=27, key=mmqYB, age=14, key=4Z3Ay, age=62, key=x3B0i, age=55, key=QCiQB, age=72, key=zGtmR, age=66, key=nlIN9, age=8, key=hKalB, age=50, key=Na33O, age=17, key=jMeXm, age=15, key=OO2Mc, age=32, key=hhowx, age=32 )
Not getting how to match value and get count.
Example Input
{"data":"key=IAfpK, age=58, key=WNVdi, age=64, key=jp9zt, age=47"}
Example Output

If anyone have idea then please let me know

Answer 1

I originally missed the over 50 part.
If your goal is to just count, and your data is as uniform as you say, you can still just search on age= followed by one or more digits using RegEx, then count the over 50 items:
$data = 'key=IAfpK, age=58, key=WNVdi, age=64, key=jp9zt, age=47';
$itemsOverFifty = [];
if(preg_match_all('/age=(?<age>\d+)/', $data, $matches)) {
$itemsOverFifty = array_filter($matches['age'], fn($item) => $item >= 50 );
}
echo count($itemsOverFifty);

This is rather messy and a REGEX person may be able to clean this up a bit, but it seems to work
function fixTheNonsenseJson($nonsense)
{
$a = json_decode($nonsense);
$s = str_replace( ['key=', ', age=', ', "key'], ['"key":"', '","age":"', '", "key'], $a->data);
$bits = explode(',', $s);
$usable = [];
foreach ($bits as $bit) {
$j = json_decode('{' . $bit. '}');
if ( isset($j->key) ) {
$t = new stdClass();
$t->key = $j->key;
}
if ( isset($j->age) ) {
$t->age = $j->age;
$usable[] = $t;
$t = null;
}
}
return $usable;
}
$badJson = '{"data" : "key=IAfpK, age=58, key=WNVdi, age=64, key=jp9zt, age=47, key=0Sr4C, age=68, key=CGEqo, age=76, key=IxKVQ, age=79, key=eD221, age=29, key=XZbHV, age=32, key=k1SN5, age=88, key=4SCsU, age=65, key=q3kG6, age=33, key=MGQpf, age=13, key=Kj6xW, age=14, key=tg2VM, age=30, key=WSnCU, age=24, key=f1Vvz, age=46, key=dOS7A, age=72, key=tDojg, age=82, key=nZyJA, age=48, key=R8JTk, age=29, key=005Ot, age=66, key=HHROm, age=12, key=5yzG8, age=51, key=xMJ5D, age=38, key=TXtVu, age=82, key=Hz38B, age=84, key=WfObU, age=27, key=mmqYB, age=14, key=4Z3Ay, age=62, key=x3B0i, age=55, key=QCiQB, age=72, key=zGtmR, age=66, key=nlIN9, age=8, key=hKalB, age=50, key=Na33O, age=17, key=jMeXm, age=15, key=OO2Mc, age=32, key=hhowx, age=32"}';
$usable = fixTheNonsenseJson($badJson);
// the actual code to do the count
$count = 0;
foreach( $usable as $u){
if ( $u->age > 50 ) {
$count++;
}
}
echo "Count > 50 = $count";
